Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.

Nissan Murano hybrid greens up Shanghai

Nothing says summertime like a muscle car with a ragtop. Or, in China's case, a hybrid crossover SUV, right? So it's a good thing Nissan plans on starting sales of a hybrid variant of its Murano in China for the upcoming warm weather season. Nissan showed off the Murano Hybrid at the Shanghai Motor Show with a supercharged engine that is paired with an electric motor. The company says the powertrain will deliver the fuel economy of a 2.0-liter engine and the power of a 3.5-liter V6 engine. Nissan didn't release actual specs of the engine nor any fuel-economy figures. Back in 2013, Nissan was working on expanding its hybrid choices, including hybrid variants for both the Murano and the Rogue. This powertrain choice makes some sense, since it could be difficult to wring a decent single-charge range out of those relatively heavier vehicles if they were all-electric. With that in mind, take a look at Nissan's press release below. NISSAN APPEALS TO CHINESE WITH TWO WORLD PREMIERES: LANNIA AND MURANO HYBRID AT AUTO SHANGHAI 2015 Lannia makes global debut to capture the hearts of young Chinese customers All-new Murano Hybrid offers excellent fuel economy and driving performance in the luxury SUV segment Customers in China can begin ordering GT-R Nismo and 370Z Nismo today SHANGHAI, China (April 20, 2015) – Nissan unveiled two all-new production models, Lannia and Murano Hybrid, along with two Nismo products, GT-R Nismo and 370Z Nismo, at Auto Shanghai 2015. "These innovative vehicles represent the start of an exciting new chapter in the story of Nissan's presence in, and commitment to, China," said Nissan President and CEO Carlos Ghosn. "Nissan's growth strategy in China will continue to reflect our commitment to use local engineering and manufacturing. And we will maintain our support for China's efforts to promote more efficient and sustainable transportation. On both of these fronts, Lannia and Murano Hybrid will lead the way forward." Highlights of the Nissan display: Building on Nissan's longstanding success in the sedan market, Lannia delivers a fresh, distinctive personality that China's young generations embody. As the first product developed and designed for the young Chinese generations, especially those in their 20s and 30s today who are seen as energetic trendsetters, Lannia is a tangible expression of the company's commitment to China.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.
